Citation: R v Lui (No 4) [2026] NSWSC 671
Court: Supreme Court of New South Wales
Date: 2 June 2026
Judge: McNaughton J
Background
The accused, Mr Pei Lui, stands trial for the murder of Mr Tao Cheng, a 25-year-old man found dead in a stairwell near a Sydney CBD gaming café in December 2022. The Crown alleges Mr Lui and a co-accused, Mr John Henry, were the only other people present in the stairwell when Mr Cheng was killed. Mr Lui's case is that he did not assault the deceased at all.
Mr Henry had previously been tried for murder, but that jury was discharged after failing to reach a verdict. Approximately three weeks later, Mr Henry pleaded guilty to manslaughter on the basis of an extended joint criminal enterprise: specifically, that he participated in an agreement to steal, and that he reasonably foresaw the real possibility that Mr Lui might assault the deceased in carrying out that agreement. The Crown called Mr Henry as a witness in Mr Lui's trial.
During cross-examination by senior counsel for the accused, Mr Henry denied that he had ever intended to steal from Mr Cheng. Senior counsel then sought to have McNaughton J include a specific direction in the summing-up, based on the proposition that Mr Henry's guilty plea necessarily involved an admission of an intention to steal.
Legal Issues
- Whether a direction should be included in the summing-up stating that Mr Henry's guilty plea to manslaughter, as a matter of law, involved an admission that he intended to steal from the deceased at the time he took the deceased's credit card.
- Whether the proposed direction accurately reflected the law of extended joint criminal enterprise.
- Whether the proposed direction would cause confusion for the jury.
Decision
Issue 1: Whether the proposed direction correctly stated the law
McNaughton J declined to give the direction on two principal grounds. First, the proposed direction did not constitute a complete or accurate statement of the law on extended joint criminal enterprise. An extended joint criminal enterprise requires proof that the accused had foresight of a real possibility that the other participant might commit a further crime beyond the agreed offence. That element was entirely absent from the proposed direction.
Second, and more fundamentally, it was not correct as a matter of law to say that Mr Henry's plea of guilty to manslaughter necessarily involved an admission that he intended to steal. The agreed facts at Mr Henry's sentencing proceedings indicated that the implied agreement to steal arose from Mr Henry's physical conduct in holding items passed to him by Mr Lui, rather than from any express or independently formed intention to steal on Mr Henry's part. As the High Court confirmed in Huynh v The Queen and R v Tangye, participation in a joint criminal enterprise can be established by presence, assistance, or other conduct furthering the agreement, with knowledge that the crime is being or is to be committed. Intention to commit the agreed crime is not necessarily the only pathway.
Issue 2: Risk of jury confusion
McNaughton J also found that, even if the direction were not outright incorrect, it would at the very least create confusion for the jury. An incomplete statement of a complex legal doctrine is liable to mislead rather than assist. The direction was therefore refused on this basis as well.
Issue 3: Remaining evidentiary matters
For completeness, McNaughton J noted that Mr Henry gave inconsistent accounts at trial compared with the version recorded in his sentencing agreed facts regarding holding the bank card. That inconsistency remained available to senior counsel for the accused to address in closing argument.
Orders Made
No formal orders were recorded in the provided text. The decision constitutes a refusal of the direction sought by senior counsel for the accused.
Key Takeaways
- A guilty plea to manslaughter on the basis of extended joint criminal enterprise does not, as a matter of law, necessarily constitute an admission that the pleader independently intended to commit the agreed underlying offence (here, theft). Participation can be established through conduct and knowledge without proof of independent intent.
- Extended joint criminal enterprise requires proof of foresight of a real possibility that a co-participant might commit a further crime beyond the agreed offence. Any jury direction on the doctrine must capture this element to be legally accurate.
- In refusing the direction, the Supreme Court emphasised that an incomplete statement of a complex legal principle risks causing confusion and should not be included in a summing-up, even where an accused contends its absence is prejudicial.
- Where a co-accused's guilty plea is placed before a jury through agreed facts, the precise legal basis of that plea governs what admissions can properly be attributed to it. Courts will scrutinise attempts to characterise a plea as carrying broader admissions than its stated basis supports.
- Inconsistencies between a witness's trial evidence and the agreed facts from their own sentencing proceedings remain a matter for counsel to address in closing argument, rather than a basis for corrective jury directions.
